Description
Technical Field
The utility model relates to the technical field of electric machine, especially, relate to a stable form stator punching.
Background
The stator punching sheet and the rotor punching sheet are key parts of the motor, and materials, inner circle size, outer circle size, groove shape size and the like of the stator punching sheet and the rotor punching sheet have direct influence on energy consumption, heat dissipation, working efficiency, noise and service life of the motor. In the motor used in the current market, the structure of the stator punching sheet and the structure of the rotor punching sheet are unreasonable, so that the operation parameter indexes of the motor are adversely affected. For example, the stator punching sheet with the publication number of CN 205829328U cannot meet the requirements of customers in terms of heat dissipation effect and energy consumption loss, and the stator punching sheet has low stability and is not suitable for being matched with a rotor rotating at a high speed.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: in order to solve among the prior art stable form stator towards piece radiating effect and energy loss can not satisfy the customer demand to and the not high technical problem of stability, the utility model provides a stable form stator towards piece, it is rational in infrastructure, satisfy the parameter index of motor operation.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a stable form stator punching sheet, including the annular towards the piece body that circles, a plurality of stator teeth of the even interval distribution of interior circumference towards the piece body, form the wire winding groove between two adjacent stator teeth, the periphery equipartition towards the piece body has four to be rectangular lugs, rectangular lug's length limit and towards the integrative structure of formation of piece body, every rectangular lug has seted up long waist hole on the surface, every rectangular lug with one side and still be provided with the right angle lug towards between the piece body periphery, round through-hole has been seted up on the surface to every right angle lug, round through-hole's area is less than the area in long waist hole.
Furthermore, in order to reduce loss, the corners of the outer sides of the rectangular lugs are in arc transition.
Furthermore, in order to reduce loss, the corners of the right-angle lugs are in arc transition.
The beneficial effects of the utility model are that, the utility model discloses a stable form stator is towards the piece, there are four rectangular lugs towards the periphery equipartition of piece body, outline after four rectangular lug combinations is roughly square, can increase the stator towards holistic stability, the area in long waist hole is greater than the area of circular through-hole, can make the air current pass through two holes and assist each other, further improve the radiating effect, reduce the motor temperature rise, reduce the heat loss, improve the efficiency, prolong motor life simultaneously, and reasonable in design satisfies the customer demand.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the preferred embodiment of the present invention.
In the figure: 1. the punching sheet comprises a punching sheet body, 2 stator teeth, 3 winding grooves, 4 rectangular lugs, 5 long waist holes, 6 right-angle lugs, 7 circular through holes.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1, is the utility model discloses the preferred embodiment, a stable form stator punching sheet, including annular towards piece body 1 of circle, a plurality of stator teeth 2 of the even interval distribution of interior circumference towards piece body 1, form wire winding groove 3 between two adjacent stator teeth 2, it has four rectangular lugs 4 to be towards the periphery equipartition of piece body 1, rectangular lug 4's length limit and towards the integrative structure of formation towards piece body 1, long waist hole 5 has been seted up on the surface to every rectangular lug 4, every rectangular lug 4 with one side and still be provided with right angle lug 6 towards between the piece body 1 periphery, circular through-hole 7 has been seted up on the surface to every right angle lug 6, the area of circular through-hole 7 is less than the area of long waist hole 5. The outer corners of the rectangular lugs 4 are in the form of circular arc transitions. The corners of the right-angle lugs 6 are in arc transition.
The utility model discloses a stable form stator punching sheet, there are four rectangular lugs 4 at the periphery equipartition towards the piece body, outline after 4 combinations of four rectangular lugs is roughly square, can further increase stator towards holistic stability, long waist hole 5's area is greater than circular through-hole 7's area, can make the air current mutually assist through two holes, the air current converges, circular through-hole 7's air velocity is bigger, promote the air current of process in the long waist hole 5, supplement each other, further improve the radiating effect, reduce the motor temperature rise, reduce the heat loss, improve the efficiency, prolong motor life-span simultaneously, and reasonable design satisfies the customer demand.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
